Dembski provides an excellent etymology of “intelligent” in his book:
The word intelligent comes from the Latin [language]. It stems from two Latin words, the preposition inter, meaning between, and the Latin . . . verb lego, meaning to choose or select. . . . According to its Latin etymology, intelligence therefore consists in choosing between. In an act of information creation, an intelligence chooses which possibility within a matrix of possibility to actualize. In the ultimate act of information creation, a supreme intelligence chooses which world among all possible worlds to actualize. The world so chosen becomes the real world. . . . Thus, for me, a nonmaterial trinitarian God is the supreme intelligence and ultimate reality. Moreover, this God creates via speech acts. God speaks and things happen. Or, alternatively, God communicates information and new possibilities are actualized.”
